COMBINATION-SHOE.

Specification of Letters Patent.

Patented Aug. 8, 1911.

Application filed April 19, .1911. Serial No. 622,111.

To all whom it may conccm:

Be it known that I, JAMES D. MOORE, a citizen of the United States, residing at North vVilkesboro, in the County of Wilkes and State of North Carolina, have invented a new and useful Combination-Shoe, 'of which the following is a specification.

This invention relates to an improvement in combination shoes, the said combination shoe and screen device being used in connection with bur wheat and corn mills, and its primary object is to provide a device of this character which is an improvement upon Patent No. 978,l88, granted December 13, 1910.

A further object of the invention is the provision of a combination shoe provided with means for receiving the grain and other particles and for separating the good grain from the bad grain, the foreign substances also from the same and delivering the good grain to the burs while the other particles are carried away and separated from the good grain.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangenent of parts and in the details of Construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. In the drawings: Figure l is a top plan view of the completed article. Fig. 2 is a view in plan of the lower portion of the shoe. Fig. 3 is a longitudinal sectional view through the clevice, taken on line X-X of Fig. l.

Referring to the drawngs, the numeral l designates the body of the shoe which may be made of the contour shown, or otherwise,

and is provided with a marginal' metallic rim 2. The body, as usual, is constructed of.

wood and is provided at its intake end or that which will be clisposed beneath the spout of the mill with a relatively large chamber 3, into which the finer products are discharged and pass out through the lateral channels 4 at the discharge end of the shoe to the burs. Mounted at the discharge end of the frame 1 and separating the channels 4 is the projection 5, having its angular or pointed end 6 toward and centrally of the chamber 3, and provided transversely across or through the projection, is a rectangular opening 7 forming a discharge for the es- 'cape of the perfect grain. Removably fitting within the body and conforming marginally to the contour of the rim 2, is a frame comprising two members 8 and 9, between which is secured a relatively coarse mesh screen 10, the member 9 having secured to its under side a relatively fine mesh screen 11, the latter having or being provided with an opening which corresponds and fits around the opening 7 of the projection 5.

The member 8 is provided with the in- .Wardly projecting walls 8', forming a chute with the member 9 as its bottom, to convey the coarse products, imperfect grain, cobs, etc., over the end of the shoe.

At that portion of the screen 10, that will come under the mouth of the mill, there is secured a circular block 12 to prevent the great wear upon the screen lO at this point and to provide for the purpose of re-gulating the feed, and if desired, of cutting off said feed, which may be accompli shed by lowering the spout of the mill, and yet still permit the shoe to vibrate and thus efect the separation of the coarser from the finer portions of the grain. The upper surface a of this block 12, is inclined toward the feed end of the shoe, thus providing a surface which will tend to reduce the glancing action of the grains as they strike therefrom after being delivered from the mill.

By making the two members 8 and 9, or what is known as the screen frame removable, a coarse screen may be used in place of a fine one and Vice versa, according to the character of grinding that it is desired to perform, and by this means one mill will be aclapted to grind flour as well as corn meal.

By this Construction it will be seen that the coarser screen will carry ofi' the larger matter such ascob ends and the like, while the finer screen will convey the grain to the Conduit leading into the burs, and at the same time allow any small trash such as silks, inferior grain, grit and the like to pass through and off of the end of the screen, the same as that of the coarse sieve.

What is claimed is l. The combination with a body provided at its intake end with a graizn receiving chamber and with two iateral discharges, a projection in the discherge end torning said lateral discharges, and provided with a grain discharge thei-ein, of a double screen removebly arranged in the body, and provided at its intake end with means 'or checking the discharge of the grain and deflecting the grain in radial directions upon the screen.

2. The combination with a body provided at its intake end with a grain receiving chamber, and with two iateral discherges, a

projection in the discharge end forming said lateral discharges and provided with a grain discharge opening thei-ein, of a double screen removabiy arranged in the body, and an imperforate means connected to and cerried by the upper screen for checking the discharge oi' the grain to the shoe and deflecting the grain radialiy upon the screen.

3. The combination with a body provided at its intake end with a grain receiving chalnber, ar projection having a pointed end mounted in the discharge portion of said body and having its pointed end projecting toward the chamber, said projection providing two lateral discharges ;tor the body, and being provided with a gru in outletwithin itself, a fraime removably mounted in the body and disposed to rest upon said projection, screens carried by said body the lower one of which is provided with an opening which empties into the outiet of the projection.

4. The combinaton with a body provided at its intake end with a grein receiving chamber, of a ;treme carrying two screens removably mounted in the body above said chnmber, and a circular impertorate block carried by the upper screen of said treme and adapted to check the discharge of grain from the mili and defiect said grain radizlly upon the screens.

5. The combinetion with e body provided at its intake end with a. grain receiving chamber, of a treme removably mounted above said chamber and provided with interposed screens, the upper screen being of a larger mesh than the lower screen which rests over the chamber, an imperforate means carried by the upper screen for checking the flow of grain from the mili and defiectin; the grain radially upon said screen,

and a restricted discharge formed by the two screens.

(3. The combination with e body provided at its intuke end with a grain receiving chamber and with two laterl discl'iarges, of a double screen removably arrnnged in the body above the chanber thereof and provided with means for checking the disci'arge of and defiecting the grain radially upon the screen, said means being :in impertorate circuhr block having an inctined upper surface.

7. The combination with a body provided at its intake end with a grain receiving chamber, a projection mounted in the discharge end of said chamber and provided with a pointed end projecting toward the chanber, said projection being provided with :i grain discharge slot transversely thereof, said projection further providing* two iaterai discharges 'for the grain receiving chamber, of it treme composed of two members renovably mounted within the body and provided with one screen upon its lower 'face to rest over the grain receivin chamber and provided with an opening to surround the discharge opening of the projection, and another screen interposed be tween the members of said treme.

8. The combination with a body provided at its intake end with a grain receiving chamber, and e projection mounted u pon said body and having e pointed end projecting toward the main portion of the chamber and providing two laterai discharges for said chamber, said projection being provided with a transverse grain discharge opening` therein, a frame carrying two screens adapted to removabiy fit in the body above the chanber, and an impertorete circular block carried by and upon the upper screen and adapted to be disposed below the discharge to receive the grain from the mili and scatter said grain equally in all directions upon the screen.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signzh ture in the presence of two witnesses.
